  Vulnerability Insight:

  It was discovered that OpenSSL was vulnerable to a double-free
  when using TLS server extensions. A remote attacker could send a
  crafted packet and cause a denial of service via application crash
  in applications linked against OpenSSL. Ubuntu 8.04 LTS does not
  compile TLS server extensions by default. (CVE-2008-0891)
  
  It was discovered that OpenSSL could dereference a NULL pointer.
  If a user or automated system were tricked into connecting to a
  malicious server with particular cipher suites, a remote attacker
  could cause a denial of service via application crash.
  (CVE-2008-1672)

  Affected Software/OS:
  openssl vulnerabilities on Ubuntu 8.04 LTS

  Fix: Please Install the Updated Packages.
